Which of the following is not peculiar behaviour of Beryllium?
Correct answer: B. It is not resistant towards complete oxidation.
- A. It is as hard as iron.
- B. It is not resistant towards complete oxidation.
- C. Its melting and boiling points are higher than other alkaline earth metal.
- D. It is the only member of alkaline earth metals which reacts with sodium hydroxide to produce hydrogen gas.
Explanation
Beryllium, in particular, is quite resistant towards complete oxidation, even by acids, because of its BeO coating. This makes Option B the correct choice. Option A is incorrect because the hardness of Beryllium is a known property. Option C is incorrect as it is true that the melting and boiling points of Beryllium are higher than other alkaline earth metals. Option D is incorrect as Beryllium is indeed the only member of alkaline earth metals that reacts with sodium hydroxide to produce hydrogen gas.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
